I suppose Google wants us to pretend that "agents" can't be "resources." MCP is already well established (Anthropic, OpenAI, Cursor, etc), so Google plastering their announcement with A2A endorsements just reeks of insecurity.
I figure this A2A idea will wind up in the infamous Google graveyard within 8 months.
